So you are saying second/third generation poles from the UK have lousy polish?
Au contraire. Many speak no Polish at all. Beyond 'lousy'. And those few who can understand a little often have very limited lexical control. Anyway, they aren't Poles; they're British people whose granny came from somewhere else, like thousands of others with a granny from Pakistan, Poland, Barbados etc. Perhaps the 'biro bandit' was one of those.
Well, a pole in the UK is a wooden or metal support. A Pole is a Polish citizen and polish is what is used when we polish something up.
Indeed. Unless of course it's
z Prus in which case we spruce it up. Perhaps the bank robber would have done better with a metal support.
This bank robbery thing is really intriguing me. Why did he come from Germany to Warsaw and why did he do it in such a ham-fisted way. He may well have a personal connection to Poland - hard to think he chose Warsaw for any other reason.
